基于多指标正交实验的并联混合动力汽车控制策略参数分析

摘要

针对并联式混合动力汽车电辅助控制策略的参数优化问题,基于多指标正交优化设计理论,以混合动力汽车的燃油消耗、CO排放量、HC和NOx的总排放量为实验指标,设计了正交优化实验表.运用直观分析法分析了18组实验结果,量化研究了控制策略参数对并联式混合动力汽车整车性能的影响,找出了各个指标的显著性影响因素.%Concerning the parameter optimization of electric assist control strategy for Hybrid Electrical Vehicles ( HEV), the orthogonal table was designed based on the theory of orthoplan experiment, which took the fuel consumption, the CO's emission, and the total emission of HC and NOX as the experimental indexes. The influence of control strategy parameters on the parallel HEV was obtained by using intuitive analysis to analyze the 18 group test results, and then the remarkably influencing factors of each index were found out.
